Lunch was eaten in the chamber of commerce, and Wei Miao, Zhang Zhao, Sun Jing and other seal engraving masters also had a meal. When Lin Muyu showed interest in seal engraving, Jin Xiaotang asked with a smile: "Brother Ayu also wants to learn seal engraving?"

"Well, I have this idea." Lin Muyu nodded.

Jin Xiaotang smiled: "The engraving masters in our chamber of commerce can teach you!"

At this moment, the arrogance on Wei Miao's face appeared again, and he held the chopsticks and said, "Tong Yu is a martial artist who practices martial arts. His attainments in martial arts are naturally beyond the reach of others, but the sealing technique emphasizes the unity of one mind and hand. If there is a slight deviation, it will fail. I am afraid that the commander may not be very easy to learn."

"Yeah?"

Lin Muyu raised her eyebrows and said, "Mr. Wei, is it so profound in engraving?"

"That's natural." Wei Miao said proudly: "Doctors of our Wei family have focused on engraving for dozens of generations, but few real engraving masters have emerged. I have practiced engraving for nearly twenty years and have been just a conductor of engraving. I am plagued by the generals and are probably difficult to calm down. If I give up halfway, it will be even worse."

"Wei Miao!" Tang Xiaoxi's pretty face turned cold and said, "Please pay attention to your attitude. The person who talks to you is the Imperial General Lin Muyu, not a servant who works in a chamber of commerce."

Wei Miao hurriedly bowed to the ground: "I...I know I'm wrong..."

"Forget it, get up, I didn't blame you." Lin Muyu raised his hand, and the pressure of the holy realm surged, and he helped Wei Miao's body up.

Qin Yin remained silent, added a piece of meat to Lin Muyu, and said with a smile: "If you want to learn to engrave, you must first have enough food."

"Thank you Xiaoyin!" Lin Muyu couldn't help but smile.

Qin Yin and Tang Xiaoxi did not reveal their identity in front of the seal engravers, but Lin Muyu's "Xiao Yin" made Wei Miao, Sun Jing and others guess something. When they vaguely felt that the talented and radiant beauty in front of them might be the empress Qin Yin, they all felt a little uneasy when they had eaten. They would never dare to move the dishes in front of the empress, and could only eat a plate in front of them. Poor Wei Miao could only finish the plate of garlic paste in front of them, and his tone was very fresh and refined.

...

At night, the library in Zetian Palace was brightly lit. Lin Muyu searched for a long time and almost dug out all the classics about engraving in the library. Several of them seemed to be of great value for studying, namely "The Theory of Engraving", "The Essence of Engraving Techniques" and "The Illustrated Record of Engraving Formation". There is no problem with these books being used to get started.

The principle of engraving is very simple. The required mysterious array is engraved on the flat-shaped metal, and then inlaid with gems to provide the energy of the mysterious array, so that the mysterious array can naturally be activated.

However, the engravings are divided into many types, from level 1 to level 7 to level 7 to more advanced. From the book "Theory of Engraving", Lin Muyu learned how powerful the engravings are. The 5th Dragon Slaying Seal provides dragon armor defense for armor, the 6th God Control Seal provides armor wearers with certain immunity to pressure, and the 7th God Killing Seal provides armor wearers with powerful divine resistance. This also means how much advantage a powerful divine realm wearing the God Killing Seal has to be against a divine realm of equal strength!

However, at present, Lin Muyu can only be regarded as an apprentice in sealing, so she can only start with level 1 engraving.

According to the engraving formation illustration, there are four main types of engravings at level 1, namely Fire Seal, Wind Seal, Cold Seal, and Thunder Seal. As the name suggests, they are to resist the power of various laws. The gems provided by these four engraving powers are red agate, sapphire, ice crystal, and amethyst. Although these gems are expensive, they are not rare.

After taking a piece of imperial guard armor, Lin Muyu started to study. According to the map on the picture book, he carefully dug out a mysterious array of fire seals with a small engraving knife. He saw strands of kingly fighting flames penetrated into the mysterious array along the knife. It was exactly what Wei Miao said about the unity of mind and spirit. When engraving, he had to pour his strength into it, otherwise he would not be able to start the engraving mysterious array.

"Bang..."

Suddenly, a corner of the mysterious formation collapsed.

"It's broken?" Qin Yin opened her bright eyes and guarded her.

"Well..." Lin Muyu looked ashamed.

"It's okay." Qin Yin laughed and handed over a piece of armor again, saying, "There are so many armors in the Imperial Guard. Brother Ayu, don't be anxious. Come slowly, you will succeed."

"good!"

Encouraged by this young girlfriend, Lin Muyu continued to cheer up and devote her energy to the engraving knife, and continued to engrave the imperial fire seal. The imperial fire seal is one of the simplest seals. If you don’t even master the imperial fire seal, then don’t mention the more advanced seal array.

By midnight, Lin Muyu had already carved seven or eight pieces of armor, but she did not give up. Her face was covered with sweat. Qin Yin helped wipe it off and patiently accompanied him.

Lin Muyu was not impatient, and carved the metal on the armor bit by bit. The engraving knife was wrapped with a faint king's flame, and carved winding patterns on the armor. Finally, this time, a perfect round fire seal was completed, and there were faint fire red lights in it. When a red agate was embedded, the seal array suddenly made a "swish" sound, and a wisp of energy poured into the seal array from the red agate!

"Success!" Qin Yin was very happy, and was happier than completing a masterpiece by herself.

Tang Xiaoxi opened the cabinet beside him, took out a special crystal rig, and said, "This is a crystal engraved, which can test the perfection of the engraved, let's try it."

When the engraved crystal covered the fire seal, the light of the crystal suddenly surged, and a number above jumped violently, and finally stayed on 32.

"Does it mean it's very strong?" Lin Muyu asked carefully.

"Not." Tang Xiaoxi burst out laughing: "This means that the perfection of this fire seal is 32%. Generally speaking... less than 50% of the engravings are failures... Mu Mu must have had problems with the technique and the engraving depth."

"Um."

Lin Muyu carefully reviewed the detailed explanation of the imperial fire seal recorded in the classics. The engraving depth is 0.7 cm. Obviously, his engraving depth is only 0.5 cm, which is still much worse. So he took another piece of armor and continued to try to carve the imperial fire seal.

Just as he had carved about 20% of the pattern, a subtle echo came from the pattern, which made Lin Muyu feel a little excited. The engraved mysterious formation seemed to have spirituality, and it actually echoed his king's battle of flames. This should be a good thing, right?

Moreover, the king's fighting flame is far stronger than the true energy used by Wei Miao, Zhang Zhao and others. Logically speaking, the seals under the king's fighting flame should be stronger than those of Wei Miao and others!

This time, a fire seal was completed in one go. After the red agate was embedded, a fiery red mysterious array suddenly appeared faintly. After testing with the test crystal, an 87% number jumped out this time!

Tang Xiaoxi and Qin Yin both opened their mouths in shock. Although they knew that Lin Muyu was gifted, they could actually complete the 87% perfect Fire Seal overnight, which was too horrible!

"No... it's impossible... it's close to 90% perfection..." Qin Yin looked at him in surprise and joy: "A Yu, you must be a genius, otherwise why would this happen..."

Tang Xiaoxi said happily: "Although it is only a level 1 engraving, it is more than 80% perfection. Basically, this work can be sold at a price of more than 1,000 gold coins in Lanyan City!"

“So expensive?”

"Well! The armor on your body is a work by Wei Miao, and the perfection of the two layers of engraving is only 67% and 72%."

Lin Muyu was very happy. It seemed that he had the talent to engrave the seal. The spiritual echo formed between him and the Fire Seal just now should be what Wei Miao said about the unity of mind and spirit. However, his king's fighting flame was much stronger than Wei Miao's true energy. Only by carving 87% perfection is worthy of his level of a Saint King-level powerhouse!

So he continued to study the Wind Control Seal, the Cold Control Seal, and the Thunder Control Seal, and tried it one by one.

The two beautiful girls actually fell asleep quietly on the table beside them. Lin Muyu did not disturb them. She just took two blankets from the Emperor's chief female official Shangguan Jingyue, gently covered Qin Yin and Tang Xiaoxi so that they would not catch a cold, and then continued to focus on their "imprinting cause".

...

The next morning, a ray of morning light shot into the table in the library. Lin Muyu slowly relieved a piece of armor in his hand. After embedded in the ice crystal, the cold seal had been activated. The test crystal showed a 93% number. Tsk, the 93% perfection was almost the same!

On the side, Qin Yin woke up and turned around and saw Lin Muyu's handsome face. She couldn't help but smile sweetly: "Good morning, Brother Ayu."

She seemed to have become accustomed to the days when Lin Muyu was around her, and she only wanted to see him every morning when she opened her eyes.

"Good morning, Xiaoyin."

Lin Muyu still left the armor behind him. When he turned around, he was startled. More than a hundred pieces of armor from the Imperial Guards were piled up behind him, most of which were scrap items and a small number of them were successful items.

"So many..." he said in shock.

Shangguan Jingyue smiled gently and said, "Yes, the imperial sweat armor in the Zetian Palace is about to be used up by you!"

"Ahem..."

Lin Muyu was very embarrassed.

Qin Yinze smiled and said, "It's okay, just let the Ministry of Works cast it. I heard that behind a successful divine seal master... there are at least tens of thousands of failed items..."

"Um."
Chapter completed!
